The biggest challenge in this game is to fill the screen with your virus in 1 color, in the least possible moves, choosing squares, hexagons or triangles. However, if you have done a few off these puzzles you've done them all. It's a repetition of the same, where the only difference is the maximum amount of moves you can make. There is no other progression or goals that you can achieve. That makes it a little boring after a short time of playing.

i love this game a lot... it has been a real challenge for me and it keeps me going back for more

Virus 3 is an older game (2005) somewhat reminiscent of map puzzles where you have to avoid touching borders with the same color territories. You can choose triangles, squares, or hexagons for your grid, and either 5, 7, or 9 different colors. The object of the game is to 'grow your virus' so that it spreads across the game board as rapidly as possible. Sounds easy? It really takes quite a bit of strategy & planning to cover the board in as few moves as possible. If you're looking for mindless entertainment to while away time, this is not the game for you, but if you're looking for a game to take your mind off of something, this one fits the bill nicely. It's quite addictive and challenging. The music is tolerable for awhile but thankfully, also mutable. No frills here, just a good little game to exercise the noggin. Definitely worth a try; enjoy!

I LOVE THIS GAME! You can change it up so that you can have between 5-9 colors, the puzzle in a whole different shape, or the actual colors in the puzzle a different shape (hard!). You can also either choose random puzzles, or stay with one puzzle in order to master it. It's great for relaxing........... i wish there were a new version!
